CAR-'AXLE LUBRICATOR.

SPECIFICATION. forming part of Letters Patent No.. 395,887, datedJanuary 8, 1889. Application filed October 9, 1888. Serial No. 287,615.(No model.) Patented in England November 7, 1887, No. 15,147.

To ZZ whom, may concern:

Be itlznown that l, 'IHonxs FREEMAN Norr FINCH, a sub ject ot' the Queenot' GreatBritain, residing' at Sidbury 'orks, lVorcester, in thefacturer, have invented certain new and useful Improvements inAppliances for Lubricating` Railway and other Axles and .lournails, (forwhich l have obtained a patent in Great Britain, No. 15147, datedNovember 7, i887) of which the following is a specification.

The object ol' my invention is to eltect iinprovements in appliancesforlubricatingraih way, tram car, and other axles and journals; and thisspecification describes the method of applying the same to railway andtram car axles, from which description its application to other kindsot' axles and journals will be readily understood.

A constant supply oi' oil orot her lubricant is applied to the journalwhile revolving by means ot' a wheel or roller fitted in a reservoir orvessel under the journal. The wheel or roller is pressed upward andretained in contact with the journal by means of spiral or other springsin such a manner as to insure such contact. The lubricant is supplied tothe box through ahole formed in the external wall of the axle-box. 'lhewheel or roller may be made ot any suitable material, and if necessarymay be covered with `felt or any other suitable substance, in order tocarry upY to the journal a larger supply of the lubricant than would besupplied by the bare wheel or roller. '.lhe wheel or 'roller is iittedwith a spindle running through its longitudinal center, the two ends otsuch spindle enteringl slots or other suitable provisions in the wallsof the axle-box, and sustained or pressed upward by the springs, or thewheel or roller may be formed with trunnions for the same purpose. Thewheel or roller revolves wholly or partially in the oil or otherlubricant and in its revolutions carries up a constant supply of thesame to the axle or journal, such supply being' continued so long,I asthe roller itself is in contact with such lubricant; and in order thatmy said invention may be particularly described and ascertainedreference is hereby made to the accompanying,` drawcounty ot'llvorcester, England, luitton-rnanuings, in which similar letters oireference indicate corresponding parts.

Figure l is a side view ol' a railway axlebox. Fig. 2 is an inside endview. Fig'. 3 is 55 an outside end view, and Fig. i is a sectionalelevation, of the same, showing,l the application of my invention torailway and tram car axles.

a is the axle; b, the axle-box; c, the axle- 6o arm.

d is an inner box litted inside the box b, and capable ot sliding,lvertically therein. lhis inner box is fitted with an axle, e, carrying`a `grooved wheel, f. Springs g g are fitted 65 under the box il, whichpress it upward, and thereby keep the wheel f in Contact with the axlec.

7i is a flexible chain or band of lea-ther or other suitable materialAformed in links or 7o sections in a similar manner to some kinds ofdriving-bamls for mai'fhinery. In some cases I prefer to use a metalchain at 7L in combination with the whcelf.

is a leather collar vfitted round the axle 75 and held by the slidingIplates m m, which plates are held together by the screws and boltsn n.

o is a screw-plug, which may be unscrewed with a square key forinserting the oil.

712 Vis a leather washer.

The oil enters the box d by the hole p and the position of the plug o isadapted to the height of the oil in the box.

The wheel f is caused to rotate by its con- 85 tact with the axle c, andbeing partly i1nmersed in oil it carries oil upward to the axle c. Thest-rap 7i also carries oil upward to the axle c, with which it rotates.

The grooved wheel f and flexible chain h 9o act in concert toefiiciently supply the lubricant to the under and upper sides of theaxle by reason of the grooved wheel revolving in superficial contactwith the under side of the axle and the chain rotating with the wheel in95 contact with the uppermost port-ions of the axle. In these respectsmy invention differs fronr those axle-boxes having a spring-pressedroller alone rotating in contact with the axle, and from thoseaxle-boxes having a traveling roo spring-chain passing over the axle andunder a roller mounted in a frame carrying a non-
